After some more testing I found out that this doesn't get triggered by all rotations, only by left and right, rotation:inverted keeps the desktop effects on. Generalising, it appears kwin doesn't handle other xrandr events which it needs to when compositing is enabled.
If I change the screen mode from my laptop (intel 945gm)'s native 1024x768 to 1024x600, to emulate a netbook, kwin's painting is badly corrupted - things are painted in the wrong place on the screen or not painted at all.
Steps to reproduce:
$ gtf 1024 600 50 (for a modeline)
$ xrandr --newmode "1024x600" 39.55 1024 1048 1152 1280 600 601 604 618 -HSync +Vsync
$ xrandr --addmode LVDS 1024x600 ("LVDS" here is hardware specific...)
$ xrandr --output LVDS --mode 1024x600
and painting is corrupted
Be ready with
$ xrandr --output LVDS --mode 1024x768

I can confirm that switching modes with xrandr/krandrtray brakes the effects on my system too tl@I7:~/Documents$ uname -a Linux I7 2.6.28-13-generic #45-Ubuntu SMP Tue Jun 30 22:12:12 UTC 2009 x86_64 GNU/Linux to reproduce - just switch to any mode using xrandr -s 1024x768 for example the effects are gone after that tl@I7:~/Documents$ kwin --version Qt: 4.5.0 KDE: 4.2.2 (KDE 4.2.2) KWin: 4.2.2 (KDE 4.2.2) Hi!
